The tile 20 attaching means comprises a resil- Figure 3 is a fragmental sectional view of a ient arm 30 having a bent body portion 3| and a wall showing a modified construction, or the ap- T-headed end 41 adapted to be inserted through 50 plication of the device to cement work. the bore 21 of the nut 26 and engaged by the Figure 4 illustrates the method employed by the transverse slot 25 of the plug 24 in such a manner invention in the construction of concrete walls in that the arm 30 may be set at any desired angle which the molds provide one or both of the finwith the rear face of the tile 20, and secured ished surfaces, from rotation by tightening the nut 26 and the 5 plug 24 within the bore 21, but allowing the arm 30 to swing on the T-headed end 4i as a pivot and as limited by the taper of the bore 2?.

To mount the tile 26 upon the grid, the arm 30 is inserted through one of the spaces ii, and the tile 20 moved to bring the arm 33 back of one of the rods l5 or 16 as the case may be to compress the bent body SI of said arm 38 between the rod and the wall board is creating friction between the rear face of the tile 26 and the front face of the rods l5 and It to retain the tile 25 in place.

It will thus be seen that the arm 30 be set in any suitable relation with the rear face of the tile 20 so that it can be engaged with the proper rod by sliding the tile 20 upon the face of the grid.

In securing the tiles 2!] adjacent to a corner, window or door casing, where it is not possible to move the tile 20 either up, down or side'wise, a clamp plate 35 is employed which is formed with a transverse opening 32 into which projects the end of a resilient latch 33 secured into the clamp as at 34, and in place of the arm 30, a straight arm 49 is employed; the clamp 35 being placed in position back of and engaging one or more of the rods and the end of the arm as is inserted through the opening 32 within which it is held from removal by the latch 33.

As shown in Figure 3, the grid is composed of the bars l5 and I6 and provided with the pins I8 projecting from one side thereof; the pins having their ends anchored in the wall board l3 and passing through and secured to a board 28 which with the wall board It forms an air space 4'1; the grid being embraced by the concrete 36.

The construction shown in Figure 4, comprises two wall boards [3 which not only serve the purposes of forming two finished wall surfaces but are also used as molds between which the concrete 36 may be poured. These wall boards 13 have secured thereto the grids l5 and I6 by the pins I8 and are spaced apart and retained together by the members 3'! which are formed with the hooks 38 engaging the grid and the plates 39 abutting the boards l3 to retain the wall boards in place.

Should one of the bushings 2i become broken out of the tile 20, a repair bushing 41 is inserted as shown in Figure '7, the body of this bushing 4| being of less diameter than the original bushing, and curved 46 where it joins the flange 42 and a tube 43 is provided to fit over the body of the bushing 4! and having its lower end slit as at 44 to form teeth 45 than when the tube 43 is forced down will curve outward following the curve 46 to form a new flange and anchor the bushing 4| in the tile 20.

Having thus described my invention, what I claim is new and desire to secure by Letters Patent, is:

1. In a building construction of the class described, comprising a wall board adapted to be incorporated into the building, a grid composed of a plurality of intersecting rods in spaced relation with each other forming penings, and

means for attaching the grid to said wall board in spaced relation therewith to provide an air space between said grid and said wall board.

2. In a building construction of the class described, comprising a wall board adapted to be incorporated into the building, a grid composed of a plurality of intersecting rods in spaced relation with each other forming openings, means for attaching said grid to said Wall board in spaced relation therewith to provide an air space between said grid and said Wall board, a series of facing members and means for securing the same to the grid.

8. In a building construction of the class described, comprising a wall board adapted to be incorporated into the building, a grid composed of a plurality of intersecting rods in spaced relation with each other forming openings, means for attaching said grid to said wall board in spaced relation therewith to provide an air space between said grid and said wall board, a series of facing members and means for securing the same to the grid, and means for adjusting the securing means.

4. In a building construction of the class de* scribed, comprising a wall board adapted to be incorporated into the building, a grid composed of a plurality of intersecting rods in spaced relation with each other forming openings, means for attaching the grid to said Wall board in spaced relation therewith to provide an air space between the grid and said wall board, a series of facing members, means for adjustably securing the same to the grid comprising a bushing mounted in said facing member, and a resilient arm adjustably secured in said bushing and adapted to engage with said grid.

5. In a building construction of the class described, comprising a wall board, a grid composed of intersecting cross bars forming openings therebetween, a series of pins secured to the intersections of said grid and to said wall board and spaced therefrom to form an air space, a series of facing members, bushings secured therein and resilient arms adjustably secured therein and adapted to be engaged with said grid to attach said facing members to said grid.

6. A device for retaining tiles and the like to walls, comprising in combination with a tile,

of a bushing secured therein, said bushing formed with a threaded bore, a plug mounted in said bore, one end of said plug formed with a transverse slot, a nut threaded into said bore upon said plug, said nutformed with an axial bore, and a curved resilient arm, one end of said arm formed Y with a bent portion adapted to be retained by said nut and the slot in said plug in an adjustable relation with the tile.

7. In a building construction of the class described, comprising a pair of mold boards and finished wall facings, of grids secured to the adjacent sides thereof, and a series of transverse separating and retaining members secured to said grids for maintaining said boards in spaced relation with each other.
